[Bug 3786] [FT] Extensibility of XQuery FT

http://www.w3.org/Bugs/Public/show_bug.cgi?id=3786

           Summary: [FT] Extensibility of XQuery FT
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Full Text

We are not agreed that we have met the extensibility requirement in the FT
Requirements document:

4.2.2 XQuery/XPath Full-Text Extensibility
XQuery/XPath Full-Text MUST use the extensibility mechanisms that exist in
XQuery and XPath for it's own extensibility.

The spec is silent on this and we should add language.

It might be as simple as: 
XQuery Full-Text is extensible by the same mechanisms (extension expressions,
pragmas, user-defined functions)that XQuery 1.0 is extensible [XQuery 1.0 3.14
Extensibility Expressions]. XPath is not extensible, but XPath Full-Text may be
extendable via its host languages.

Or we may want to say/do more:
We may have extensibility on the level of XQuery expressions, but do we 
have extensibility on the level of the FT operators, the operators that 
operate on AllMatches instances?
